Gummy ruler/ Industial design

This is a kind of gluey paper with scales marked on one side。 We can use it to make a ruler when there is no ruler or the marks on ruler are not clear。If we stick the gummy paper on a straight object like cards， and then write numbers on it， we will make a ruler。 Besides，its a convenient way to get a ruler and also reduce the use of plastic in daily life。
